I forgot to upload the photo of the completed device

@MiKa oh.. pdf doesn't have some component names, sorry. I will try to share bom today. And of course I will update schematic after I test the board if needed.

@NeverDie I bought this lens in the radio shop next street It is very difficult to buy something in my country so I hope it will be not so hard to find such lens in China.

@NeverDie No problem

@gohan Imho - TS100 is beautiful toy, nice gadget, but not really useful tool. TS100 iron has much less ergonomics in comparation with others soldering stations. I recommend buy it only as extra tool, not main tool

@scalz OK, waiting your results. For now I've just found some information about tx power:
nrf24: nominal - 0dbm, max - +4dbm
nrf51: nominal - 4dbm, max - +6dbm
Not very high power

@alexsh1 You can fit juper (or any small wire, R10 on the schematic) or remove LDO at all and short top two pads.

@alexsh1 There is no problem to use your capacitors. 1206imp = 3216metric (type A) so they are fit perfect
About consumption... This is quite universal board. If you plan to use CR2032 battery it can be worth to omit LDO. You can do it using existing 0603 jumper footprint near right storage capacitor.

@alexsh1 you can solder one or two capacitors ~50-200uf. But you should remove both because we do not know which of them is bad. Do not forget about polarity Dot-key on the board means positive, so tantalum has positive key, but electrolitic capacitors has negative key.

@alexsh1 said in 💬 Button size radionode with sensors swarm extension:

...
After a one time measurement it goes to sleep automatically.

I have tried above, but still getting 0.14mA consumption in a sleep mode. Very odd!

I've read the claws library briefly again. I'm a litte doubt that this code:

_delay_ms(10);

is enough to ensure correctly timings and sensors work
